voltage-gated sodium channel activity involved in cardiac muscle cell action potential
Go to external page http://purl.obolibrary.org/obo/GO_0086006
Enables the transmembrane transfer of a sodium ion by a voltage-gated channel through the plasma membrane of a cardiac muscle cell contributing to the depolarization phase of an action potential. A voltage-gated channel is a channel whose open state is dependent on the voltage across the membrane in which it is embedded. [ GOC:mtg_cardiac_conduct_nov11 GOC:BHF ]
